Cedar impression siding corner

ABSTRACT

A corner piece for covering the corner of a structure with mating walls having siding panels containing multiple shingle impression courses attached thereto includes a first wall having an exterior face with first and second lateral edges and a second wall having an exterior face with first and second lateral edges. The exterior faces of the first and second walls include an ornamental appearance containing a plurality of vertically stacked shingle impressions. The shingle impressions of the exterior faces are staggered at least along the second lateral edges. These staggered shingle portions overlap at least a portion of the siding panels when the siding panels and corner piece are attached to the structure. The staggered shingle portions and multiple shingle impression courses of the siding panels cooperate to give the appearance that the corner piece substantially blends into the siding panels.

FIELD OF THE INVENTION

[0001] This invention relates to siding products generally, and more particularly to siding comers having cedar impressions formed thereon.

BACKGROUND OF THE INVENTION

[0002] Wooden shingles and shakes are very popular and attractive siding products used in the construction of homes, businesses and other structures. Unfortunately, these wooden products require constant maintenance, and are extremely expensive, as well as labor intensive to install. Further, the durability of wooden products, such as those constructed from cedar, lags far behind that of products made of synthetic materials. Therefore, a considerable number of synthetic siding products have been created that simulate the wooden appearance of, for example, cedar shingles or cedar shake shingles. Thess siding products are typically formed from materials such as polyvinyl chloride and polypropylene.

[0003] Once siding panels are installed onto the exterior sheathing of a structure, it often becomes necessary to place a corner cap over the exposed ends of the siding panels. Efforts have been made to match the ornamental appearance of the siding panel with the corner cap appearance, so as to avoid an unaesthetic or artificial looking final structure. One example is the simulated shake siding corner described in U.S. Pat. No. 4,015,391 to Epstein, et al. entitled “Simulated Cedar Shake Construction,” issued Apr. 5, 1977, the entirety of which is hereby incorporated by reference herein. Epstein describes simulated cedar shake siding panels that are attached to the outside walls of a structure and a corner piece 70 that may be used in conjunction with the described siding panels.

[0004] The Epstein corner 70, illustrated in FIGS. 1A through 1F, is formed with a shake impression thereon in order to match the shake appearance provided by the siding panels, also described in Epstein and shown in FIG. 1F. The siding corner 70 simulates two shakes 71,73 nailed or otherwise mitre attached at about 90°, one to the other. The corner piece 70 is formed with the horizontal base 72 approximating in size the normal depth of natural shakes. A vertical lip 74 extends from the inside edge of horizontal base 72 and locks two overlapping corners 70 when it engages slot receptor 80 formed between the base of nose 78 and planes of the preapertured nailing tab 76. Two corners 70 may be interfitted butt-end to head-end when the lip 74 is received inside slot receptor 80, as illustrated in FIG. 1C. The shake faces 71, 73 are angled forward from top to bottom so that the lip 74 can enter slot receptor 80 of the next lowest corner 70. The nailing tab 76 seats against the wall surfaces and may be nailed thereto. FIG. 1F is a plan view of a siding facade including a plurality of stacked comers 70, one on top of the other, with the shake faces 71,73 overlapping the side edges of simulated shake panels 97, 95, 91, 93 nailed to two walls of a structure.

[0005]FIG. 2A of the Epstein '391 patent is a front perspective view of another prior art multiple course simulated cedar shake corner piece 100, and FIG. 2B is a right side elevational view of the corner of FIG. 2A. The corner piece 100 includes two faces 102, 104 having a pair of vertically stacked shingle impressions thereon. The corner piece 100 includes two nailing flanges 106, 108. The corner piece 100 is nailed to a corner of a structure prior to attaching siding panels, which overlap the nailing flanges 108, 106 of the corner piece 100.

[0006] Prior art corner pieces, such as corner pieces 70, 100 described above, suffer from several drawbacks. First, referring to FIG. 1F, when viewing a corner of a structure covered by a stack of a plurality of corner pieces 70 such that both walls of the structure that form the corner are visible, the appearance of a random selection of shingles within each course formed on the siding panels does not continue through to the corner pieces 70 when the corner pieces 70 each have identical faces 71,73. The courses do not appear as if they terminate in a natural manner at the corners of the structure. This unnatural appearance occurs when employing either the multiple course corner piece 100, where the faces 102, 104 are identical, or when employing the single course corner piece 70, where the faces 71, 73 are identical.

[0007] Further, as best illustrated in FIG. 2B, when viewing only a single wall of a structure that includes a prior art corner piece 70 or a prior art corner piece 100, it becomes quite apparent that artificial corner pieces have been employed. A continuous and non-staggered lateral edge 10 is apparent along the entire corner of the structure from corner piece 70, 100 to corner piece 70, 100 when corner pieces 70, 100 are attached to the structure in a vertical stack, one on top of the other. The linear joint formed between the siding corner pieces and the siding panels is apparent to even a casual observer.

[0008] Therefore, there remains a need for a corner piece that provides the appearance of a more natural termination of the courses of a siding facade employing simulated cedar impression siding panels and for a corner piece that more effectively blends the corner piece into the facade to mask the presence of the corner piece and promote the overall desired appearance of a random selection of individual shingles.

SUMMARY OF THE INVENTION

[0009] The present invention provides a corner piece for covering a corner of a structure defined by two mating walls of the structure and for use in conjunction with siding panels containing multiple shingle impression courses fastened to the mating walls. The corner piece includes first and second walls, each wall having an exterior face, an interior face, and first and second lateral edges. The second wall meets the first wall at a corner defined by the first lateral edges. The exterior faces of the first and second walls include an ornamental appearance containing a plurality of vertically stacked shingle impressions. The shingle impressions of the exterior faces are staggered at least along the second lateral edges, and the staggered shingle portion overlaps at least a portion of the siding panels when the siding panels and the corner piece are fastened to the structure.

[0010] The staggered shingle portion and the multiple shingle impression courses of the siding panels cooperate to give the appearance that the corner piece substantially blends into, or is a virtual part of, the siding panels. The corner piece provides a natural looking termination to the courses of the siding panels when viewing the structure from the side (i.e., when only one of the walls is visible) or when viewing the corner of the structure (i.e., when both of the walls of the structure are visible). No linear seem or joint is conspicuously formed between the corner piece and the siding panels, thereby masking the presence of a prefabricated and artificial corner member.

[0011] The above and other features of the present invention will be better understood from the following detailed description of the preferred embodiments of the invention that is provided in connection with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0031]FIG. 3A is a side perspective view of an exemplary embodiment of an outside corner piece 200 for covering an “outside” corner of a structure. By “outside” corner piece, it is meant that the corner piece is shaped to cover an outwardly protruding or “outside” corner of a structure as opposed to an inwardly formed or “inside” corner of a structure, as may be covered by the inside corner piece 300 shown in FIGS. 4A-4E.

[0032] The outside corner piece 200 includes a first wall 202 and a second wall 212. The first wall 202 is defined by an exterior face 204, an interior face 206, a first lateral edge 208 and a second lateral edge 210. Likewise, the second wall 212 is defined by an exterior face 214, an interior face 216, a first lateral edge 218 and a second lateral edge 220. The second wall 212 meets the first wall 202 at a corner defined by the first lateral edges 218, 208 of the second wall 212 and first wall 202, respectively.

[0033] The exterior faces 204, 214 of the first and second walls 202, 212 each include an ornamental appearance containing a plurality of vertically stacked siding impressions formed thereon; preferably, a plurality of vertically stacked shingle impressions formed thereon; and more preferably, a plurality of vertically stacked cedar shingle impressions 230 formed thereon. Detailed impressions may be formed on the exterior faces 204, 214 by injection molding the corner piece 200. The preferred materials for forming the corner piece 200 include polyvinyl chloride (PVC) and polypropylene, although other materials such as cement, wood-polymer blends, etc. may also be suitable. The vertically stacked shingle impressions preferably match and align with the courses formed on the siding panels attached to the walls of the structure. By “course,” it is meant a continuous horizontal siding layer of brick, masonry or shingle.

[0034] An exemplary outside corner piece 200 preferably includes fastening means for attaching the corner piece 200 to the corner of the structure. Siding panels that also include a shingle impression are attached to the walls of the structure, such as in a conventional nailing fashion and preferably before attaching corner pieces 200. Once the siding panels are attached to the walls of the structure, a first corner piece 200 may be disposed at the bottom-most end of the corner of the structure. The siding panels are disposed to leave the corner of the structure partially uncovered, at least enough to accommodate the width, designated “W” in FIG. 3B, of the nailing flanges 222 described hereafter. The corner piece 200 may then be attached to the corner of the structure using the fastening means. An exemplary fastening means includes at least one nailing flange 222 extending from the first and second walls 202, 212. The nailing flanges 222 are preferably pre-apertured as shown in FIGS. 3A-3E in order to facilitate attachment to the structure.

[0035] Once a corner piece 200 is attached to a corner of a structure as described above, a second corner piece 200 may be attached above the first corner piece 200 such that the bottom end of the second corner piece 200 is fitted over the top end of the first corner piece 200 as described hereafter. An exemplary corner piece 200 preferably includes cooperable catch means for securing corner pieces together. A second corner piece 200 may be fitted over a first corner piece 200 such that catches 224 b disposed toward the bottom end of the second corner piece 200 fit into catches 224 a disposed toward the top end of the first corner piece 200. The second corner piece 200 may then be nailed to the corner of the structure as described above. This assembly technique may be followed until the entire corner of the structure is covered by stacked corner pieces 200.

[0036] It should be apparent that the bottom of the second corner piece 200 covers the nailing flange 222 of the corner piece 200 immediately below it. The corner pieces 200 are also preferably attached to the corner such that the second lateral edges 210, 220 overlap at least a portion of the siding panels when the siding panels and corner piece 200 are attached to the structure. The siding panels are preferably attached, such as by nailing flanges, to the walls of the structure prior to attaching the corner pieces 200, but the siding panels may also be attached to the walls of the structure after attachment of the corner pieces 200 if the edges of the siding panels are slid under the second lateral edges 210, 220 of the corner pieces 200.

[0037] An exemplary corner piece 200 may be approximately 14″ tall, although the present invention is in no manner limited to a specific size of corner piece. This exemplary size of corner piece 200 may be manufactured in a conventional injection molding process. Each shingle impression of the plurality of vertically stacked shingle impressions 230 of exemplary corner piece 200, therefore, is approximately 7″ tall and designed to align with the courses of the siding panels. An exemplary corner piece 200 is also preferably approximately 0.125″ or less in thickness, designated “T” in FIG. 3E, such that the walls 202, 212 of the corner piece 200 do not significantly protrude from the faces of the siding panels when covering at least a portion of the siding panels.

[0038] This exemplary corner piece 200 provides several benefits. The corner piece 200 may be attached to the corner of the structure after attaching the siding panel, as opposed to the prior art corner piece 100 shown in FIGS. 2A and 2B which must be attached to the corner of the structure prior to the attaching the siding panels. This feature, therefore, allows a damaged siding corner piece 200 or plurality of damaged siding corner pies 200 to be removed without the added labor associated with removing and reattaching the siding panels of the attached to the structure.

[0039] Also, as can be seen in FIGS. 3A-3E, the shingle impression of the exterior faces 204, 214 are staggered at least along the second lateral edges 210, 220. By “staggered,” it is meant that the second lateral edges of two vertically stacked shingle impressions are offset a distance from each other where the bottom of a first vertically stacked shingle impression meets the top of a second vertically stacked shingle impression such that one of the shingle impressions effectively extends to overlap a greater portion of a siding panel attached to the structure when the siding panel and corner piece 200 are attached to the structure. For example, the second lateral edges 210, 220 of each shingle impression 230 shown in FIG. 3D are offset a distance “S”. This distance “S” (shown in FIG. 3D), for example, may be an approximately 1.5″ to 2.0″ offset.

[0040] These vertically stacked shingle impressions align with the courses of the siding panels and overlap at least a portion of the siding panels. The staggered edges 210, 220 effectively hide the intersection between a stack of corner pieces 200 and the siding panels, and no continuous straight line intersection, as described above in connection with the prior art corner piece 100 and shown in FIG. 2B, is formed. The second lateral edges 210, 220 cooperate with the plurality of vertically stacked shingle impression 230 to give the appearance that the corner piece(s) substantially blend into the adjacent siding panels and continue the shingle courses formed thereon. No seam between the siding panels and the corner pieces 200 is discernible.

[0041] The exterior faces 204, 214 of an exemplary corner piece 200 are also preferably angled from top to bottom as shown in FIGS. 3A-3E along each of the plurality of vertically stacked shingle impressions formed thereon. The bottom edge of a first shingle impression 230 is offset a distance designated as “X” in FIG. 3D from the top edge of a second shingle impression 230 stacked below the first, as shown in FIG. 3D. This offset creates the appearance that the bottom edge of the first shingle impression overlaps the top edge of the second shingle impression and also creates an aesthetic shadow effect. An exemplary offset distance “X” is approximately 0.375″.

[0042]FIGS. 4A through 4E illustrate an exemplary interior corner piece 300. The reference numbers of FIGS. 4A through 4E correspond to the features of exemplary outside corner piece 200 described above, only with a prime following each reference number.

[0043] Although various embodiments have been illustrated, this is for the purpose of describing, and not limiting the invention. Various modifications will become apparent to one skilled in the art and are within the scope of this invention described in the attached claims.
